• The MSM is an explanation of how memory works in terms of three stores: sensory register, short-term memory and long-term memory.
•  It suggests that information initially comes from our senses and flows through a sequence of stages. 
• Things in the environment enter the sensory store. This store can handle information that is auditory, visual, tactile etc but has a very short duration of less than 0.5s. Information can be lost from the sensory store by fading away (decay).
• Only if a person pays attention will the information move into the short-term memory store, this store has a capacity of 5-9 chunks of information and a duration for up to 30 seconds.
• Adding meaning to the information through elaborative rehearsal can move it to the long-term memory store. Long-term memories can be retrieved and remembered by bringing information back from the LTM into the STM. LTM has a potentially unlimited capacity and infinite duration
• Information in the long term memory can be lost however through displacement or interference.
